UIScrollView指定区域不滑动

假如UIScrollView上有一个色盘colorView，在滑动色盘上的按钮和滑动色盘改变选中颜色时，底部的scrollView不滚动。
设置UIScrollView的属性：scrollView.delaysContentTouches = NO;
那么在自定义colorView中实现类似如下方法：

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
    
    NSLog(@"TestView touchesBegan");
    UITouch *touch = [touches anyObject];
    CGPoint point = [touch locationInView:self];
    CGRect rect = self.iamgeView.frame;
    if (CGRectContainsPoint(rect, point)) {
        NSLog(@"touchesBegan=========");
        if ([self.nextResponder isKindOfClass:[UIScrollView class]]) {
            NSLog(@"touchesBega--------");
            [(UIScrollView *)self.nextResponder setScrollEnabled:NO];
        }
    }
}


- (void)touchesEnded:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
    
    if ([self.nextResponder isKindOfClass:[UIScrollView class]]) {
        NSLog(@"touchesBega--------");
        [(UIScrollView *)self.nextResponder setScrollEnabled:YES];
    }
}

注意要设置：scrollView.delaysContentTouches = NO;否则colorView的点击事件不会执行。

另外如果同一个UIScrollView的部分子view需要快速响应事件，有的不用快速响应事件，那么需要用:

//自定义UIScrollView中
- (BOOL)touchesShouldBegin:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event inContentView:(UIView *)view {

    return YES;
}

- (BOOL)touchesShouldCancelInContentView:(UIView *)view {

    return YES;
}

如果需要在滑动时，点击在button上响应滑动事件，在UISlider上响应UISlider的滑动事件那么需要做如下设置:

//scrollView设置
scrollview.delaysContentTouches = NO;

//自定义scrollView中
- (BOOL)touchesShouldCancelInContentView:(UIView *)view {
    return YES;
}
